One of Engadget's readers says he's seeing an unlimited video streaming section to complement the current AmazonVOD options. "According to our tipster, the option has disappeared from his page as well," updated Engadget in the article. Currently, this idea is sustained by one screenshot, and there's no other report out there that hints to such a course.

Amazon appears to be readying a service that would make 5,000 movies
and TV shows available to watch instantly ,at no extra cost, to
members of the online retailer's $79-per-year Prime free-shipping
membership program.

At this time, Amazon offers a selection of more than 75,000 movie and TV
show rentals or purchases through PCs, Microsoft's Xbox 360 and Connected TV devices, including those from TiVo, Samsung, Sony,
Panasonic, Vizio and Roku. The instant-streaming service from
Amazon would add to the growing amount of premium video content
available online under a subscription plan.

The sound you likely hear
right now is the sound of Netflix crying from its headquarters in Los
Gatos, California, as the most inexpensive Netflix streaming plan costs
one $96 per year at minimum. Netflix, however, does get the last laugh
in the device diversity department, as its service allows one to stream
entertainment to more systems than just one's PC. So does Amazon's, but
there's no indication that Amazon would be bundle its unlimited
streaming service to a larger variety of devices like, say, an Xbox 360
or PlayStation 3 console, or the wide variety of set-top players
currently supporting Netflix exclusively (including the Apple TV).

Netflix, as well, carries the lion's share of available titles to stream: 28,000 in all, versus the alleged 5,000 coming to Amazon's "free" service.
